电除尘器灰斗蒸汽加热改造设计与研究

摘要

为了更有效地进行低低温改造，首先对电除尘器低低温改造时灰斗加热改造的原因进行了分析，然后对电加热和蒸汽加热的经济性等特点进行了比较，并由此提出了一种灰斗蒸汽加热改造方案。该改造方案包括灰斗筋局部割出缺口，盘管及保温设置等。使用ANSYS Workbench 软件对改造中原灰斗的主筋和次筋割出缺口后的最危险工况进行了静态性能分析，结果表明强度满足要求。最后通过实际工程证明该改造方案是安全可靠的。%Steam heating transformation is one of the main content of low -low temperature electrostatic precipita-tor transformation(LLT-ESP).It analyzes the reasons for steam heating transformation and compares with steam heating and electrical heating .Then, it designs a project of steam heating transformation and calculates the strength of the most dangerous load case in ANSYS Workbench .The practical engineering applications show that the steam heating transformation is safe and reliable.
